Can someone please explain this problem?
Consider the experiments involving rolling a single die once. Give the probabilities of the events described. Suppose that an experiment has five separate mutually exclusive outcomes: A,B,C,D and E. If the sample space for the experiment is a uniform sample space, what is P(A or E)?
Thanks for the help.

P(AorE) means getting one of two choices out of a set of five.

P(AorE)=2/5

exactly, say it was a 5 sided dice, each side labeled A-E.

P is probability, what is the probability of rolling an A OR an E the shorthand notation being P(AorE) the answer should be given as a decimal, 1 meaning that the outcome is certain to happen, 0 meaning there is no chance of this happening
